Abstract

A method of locating peripheral device applied to an electronic device is disclosed. The electronic device is connected or electrically connected to a peripheral device. The method includes: obtaining a first location information via a locating unit; when the first connecting unit is connected to the second connecting unit, sending the first location information to the peripheral device; after the first connecting unit and the second connecting unit are separated, obtaining the first location information sent by the second transmitter via the first transmitter; obtaining a second location information via the locating unit; comparing the first location information and the second location information to determine the relative position of the electronic device and the peripheral device.

First claim

What is claimed is:

1. A method of locating a peripheral device, applied to an electronic device, wherein the electronic device is electronically connected to the peripheral device, the electronic device comprises a locating unit, a first connecting unit, a first transmitter and a display system, and the peripheral device comprises a second connecting unit and a second transmitter, the method of locating the peripheral device comprising:
via the locating unit, obtaining a first location information;
when the first connecting unit is connected to the second connecting unit, sending the first location information to the peripheral device;
after the first connecting unit and the second connecting unit are separated, receiving the first location information sent by the second transmitter via the first transmitter;
via the locating unit, obtaining a second location information; and
comparing the first location information and the second location information to determine a relative position of the electronic device and the peripheral device.

2. The method of locating a peripheral device claimed in claim 1 , further comprising:
displaying the relative position on the display system.

3. The method of locating a peripheral device claimed in claim 2 , further comprising:
receiving a command to display the relative position on the display system.

4. The method of locating a peripheral device claimed in claim 1 , further comprising:
receiving a command to stop receiving the first location information; and
controlling the first transmitter to stop receiving the first location information sent by the second transmitter.

5. The method of locating a peripheral device claimed in claim 1 , further comprising:
after the first connecting unit and the second connecting unit are separated, receiving a command to send a first location information request.

6. The method of locating a peripheral device claimed in claim 5 , wherein the step of receiving the first location information sent by the second transmitter via the first transmitter after the first connecting unit and the second connecting unit are separated further comprises:
via the first transmitter, sending the first location information request to the second transmitter to cause the peripheral device to send back the first location information according to the first location information request.

7. The method of locating a peripheral device claimed in claim 6 , further comprising:
receiving a command to stop sending the first location information; and
via the first transmitter, sending a request to stop sending the first location information to the second transmitter to cause the peripheral device to stop sending the first location information according to the request to stop sending the first location information.

8. The method of locating a peripheral device claimed in claim 6 , further comprising:
when the first connecting unit is connected to the second connecting unit, setting up a first code lock in the peripheral device, wherein the first code lock can be unlocked via a first code information;
wherein the step of receiving a command to send a first location information request after the first connecting unit and the second connecting unit are separated further comprises: obtaining a first code;
wherein the step of receiving the first location information sent by the second transmitter via the first transmitter after the first connecting unit and the second connecting unit are separated further comprises: via the first transmitter, sending the first code to the second transmitter for the peripheral device to compare the first code and the first code information;
wherein after the peripheral device compares the first code and the first code information, the method of locating peripheral device further comprises:
if the first code matches the first code information, then via the first transmitter, receiving the first location information sent back by the second transmitter, wherein the first code lock for the first location information is unlocked.

9. The method of locating a peripheral device claimed in claim 8 , wherein the step of setting up a first code lock in the peripheral device when the first connecting unit is connected to the second connecting unit, wherein the first code lock can be unlocked via a first code information, further comprises: setting up a second code lock which can be unlocked via a second code information;
wherein the step of receiving the first location information sent by the second transmitter via the first transmitter after the first connecting unit and the second connecting unit are separated further comprises: encrypting the first location information by the second code lock;
wherein the method of locating peripheral device further comprises:
obtaining a second code; and
comparing the second code information and the second code; if the second code information matches the second code, decrypting the first location information which is encrypted by the second code lock.

10. The method of locating a peripheral device claimed in claim 1 , further comprising:
displaying a start code inputting interface on the display system, wherein the start code inputting interface is encrypted by a start code information;
receiving a start code via the display system;
comparing the start code information and the start code; if the start code information matches the start code, unlocking the start code inputting interface or displaying a first mode menu on the display system;
if the display system displays the first mode menu, receiving a first selection command via the display system;
comparing the first selection command to determine if a first code is used, if so, displaying a second mode menu on the display system;
receiving a second selection command via the display system; and
comparing the second selection command to determine if a second code is used.

11. The method of locating a peripheral device claimed in claim 1 , wherein the step of sending the first location information to the peripheral device when the first connecting unit is connected to the second connecting unit further comprises:
at a specific interval, sending the first location information to the peripheral device.

12. An electronic device, for electrically connecting to a peripheral device, wherein the peripheral device comprises a second connecting unit and a second transmitter, the electronic device comprising:
a locating unit, used for obtaining a first location information and a second location information;
a first connecting unit, used for sending the first location information to the peripheral device when connected to the second connecting unit;
a first transmitter, used for receiving the first location information sent by the second transmitter after the first connecting unit and the second connecting unit are separated;
a first processing unit, electrically connected to the locating unit, the first connecting unit and the first transmitter, wherein the first processing unit is used for comparing the first location information and the second location information to determine the relative position of the electronic device and the peripheral device; and
a display system, electrically connected to the first processing unit, wherein the display system is used for displaying the relative position.

13. The electronic device as claimed in claim 12 , wherein the display system is further used for receiving a command; after the display system receives a command to display the relative position on the display system, the display system displays the relative position; after the display
